Can I get pregnant from..

I gave my boyfriend a blowout.. And instead of erupting.. In my mouth(how we usually do it) he erupted.. Everywhere.. After like an hour or 2..we were making out and stuff and I wanted him to feel how wet I was so like.. I rubbed his.. Penis.. Over my vaginal hole? But it didn't go in.. It didn't.. Is there a possibility.. That can cause me to get pregnant?
